VINYL CHLORIDE MONOMER

Chlorinated hydrocarbons (CHCs)

More resilient to biodegradation, unlike simple hydrocarbons

Man-made CHCs are beginning to accumulate in theenvironment.

BASIC IDEA BEHIND THE PRODUCTION OF VCM

PRODUCTION OF VCM IS ESSENTIAL TO THE PRODUCTION OF POLYVINYL

CHLORIDE Many CHCs are created during the production of PVC this is

a growing concern.

VCM needs to be produced in a way that will minimize ortotally eliminate the release of CHCs into the environment.
